This invention relates to. a machine for assembling loose partitions in a carton such,

'for example, as is suitable for the reception .of eggs.

A carton of the general type for which the present machine is adapted is set forth in the Coyle Patent No 1,327,946, of

. January 13, 1920, this being merely a suggestive construction in this connection.

The carton herein set forth consists of a blank which is doubled over along its longitudinal center and which is provided in each of its two sections with registering transverse slots through which are inserted loose partition members As these partitions are several in number for each carton, it follows that the operation of setting these partitions in place involves considerable time and effort. It is with a view to expediting this assembly of the partitions in such a carton that the present machine has been designed.

An exemplification of the present inven- I tion'is set forth in the accompanying drawings in the manner following:

Figure 1 is a vertical section through a table or bench whereon is mounted the present machinewhichis shown in elevation;

Fig. 2 is a horizontal section therethrcugh on line 22 of Fig. 1;

Fig. 3 'is a detail in perspective of the gauge which centers the carton 'blank in position for reception of the partitions;

Fig. 4 is a side elevation of the machine looking toward the side opposite from that which appears in Fig. 1;

Fig. 5 is' a front elevation of the machine;

Fig. dis a vertical section therethrough taken on line 6--6 of Fig. 2 looking in the direction of the arrows;

Fig. 7 which is a view similar to Fig. 2 shows the parts moved to advance the partition through the carton blank;

Fig. 8 is a detail of certain of the parts shown in Fig. 7,and shows the carton blank laterally shifted after insertion of the par titions therein;

Fig. 9 is a perspective view showing the carton blank with the partitions assembled therein; and

Fig. 10 is a transverse section through the carton fully set up with the cross partitions forming individual pockets for the reception of eggs or other commodities.

The carton blank herein shown is doubled upon itself as at 11,. preferably along its longitudinal center, so as to provide adjacent sections through which a'reformed a plurality of registering slots 12 transversely disposed. Each of these slots terminates short of the folded edge 11 when the material may be' slightly cut away to provide recesses 13 which are aligned with the slots. YVith a carton blank so constructed partitions B are assembled, one for each slot. As shown, each partition is in'the form of a card having a generally rectangular shape with a central slot 14 extending inwardly from one edge. For a portion of its length one of the walls defining this slot is obliquely disposed as at 15. The opposite slot wall continues straight until close to the card edge where an offset is provided in the form ally extending pedal 25 adapted, when depressed, to engage with the proximate end of the treadle lever 22 whereby to move the same. A spring connection 26 extending between the treadlc 22 and the table 20 normally holds the former in an upward position, and by means .of a similar spring connection 27, which extends upwardly from the pedal lever 24, this latter element also is normally maintained in an upper position.

The upper end of the spring connection 2-7 is joined toa bell ,crank 28 pivoted as at 29 to' a fixed part of the machine. A link connection 30 also extends between the upper end of the treadle lever 22 and a pusher bar 31 slidably mounted Within bearings 32 to reciprocate certain parts within the machine. As by means of adjustable stops 33 the movement range of the pusher bar can be defi- Elm the frame wall 36. v Each bla e at. itsouter ing for a"blade 38 which extends laterally of the pusher head and throu h slots 39'. in

'- end may' bebent upon itself as at 40 so as to embrace loosely one edge of a guide'plate 41 carried between respective front and rear ried thereby. I Upon theside ofthe machine opposite to walls 42 and 43 whichare supported adjacent the ends of the frame wall- 36. The

.front wall is, .bypreference, not quite per pe'ndicular to the line of movement of the pushenrod 31 and ejecting blades 38 car'- that shown in. Fig. 1 are certain compartments which are defined by the several guide plates 41. Preferably a swinging frame tively, each having a .pivotal"mountin affording a partial closurefor these compartments is also provided and for this pur pose I have shown two vertical bars 45 in spacedrelation having their ends supported in'uppera'nd .lower'arms 46 and/l7. respec- ,-atj;f,48. upon a fixed part of the -mac ine frame. Upon each ofthe guide plates may 1 v.be: stacked a quantity of partition members B, a weight plate 49 being rested uponeach stack,xif desired. By closing the swinging frame which consists of the vertical bars'45, these several stacks of cards are held against accidental displacement.

Adjacent one side of the front of the machine IS a vertically extending shaft. 50 theends of .which are rotatively carried within upper'and lower bearings 51. f Mounted on the shaft near its lower end is a pinion 52 in meshi'n relation with a rack bar 53. This rack ar is extended rearwardly along oneside of the machine, as indicated in Fig. 1-,. for connection'with a spring 54 which tends to draw the bar rearwar'dly. Extending laterally. from the shaft 50 are a plurality of bars 55 one for. each card stack on the guide plates 41. The swinging ends of these barsmay be connected to a common vertical bar 56. These several bars form, in.

I itself, as shown in Figs. 7 and 8, may be is assured by means of 'a single gauge which,

brought to operative position against a pair of stops 60 which center the work horizontally. The vertical positioning of the blank as shown best in Fig. 3, may comprise a thin blade 61 extended laterally. from an arm 62 whichis carried upon the end plate 42 in.

line with one ofthe slots 63 therein through which the partition members are projected.

(With the work so positioned, pressure is thereupon applied to the pedal 25 which (1) swings the gate .aroundto hold the work against the plate 42, and (2) projects a plurality of partition members in unison, one. through each of the several slots .12 which are formed in the carton blank. As viewed in plan, thegate bars 55 are slightly bent as at 65 to provide work engaging points which are relatively close to the tranls verse middle of eachpartition member.

desired the front wall 42 may be equipped withrest plates 66 slightly bent or recessed .in conformity with 'the bars of the gate,"

whereby the carton blank'is permitted to flex inwardly near its middle at such time as the partition members are to' be inserted therein. 'With' advance of they partition members, one corner. of each will first enter a slot of'the carton blank which initially is aligned with the end plate 42. After the partitions have been advanced to their limit, the blank is then shifted laterally, as viewedin Fig, 8, and swungaround into alignment with the central slot 14'ofthe partitions, and-by reason of this blank movement all the partitions are-then interlocked gwith the blank at one extreme end of the slots12. l The advantages of. the resent machine are that it facilitates assem ly of the partition members into the carton blank.- Were.

this operation to be-performed .by' hand, it would be necessary to handle each of these partitions separately. With the present machine, however, all the partition members are correctly positioned in one operation.

This is, accomplished expeditiously, and always with a unifomnity which is sparing of damage to the carton.
